In this article a lumped-parameter heat transfer model and an air flow model of a typical Axial Flux Permanent Magnet (AFPM) machine is presented. The application of the proposed models to an AFPM generator is described in detail. The calculated results are compared with the measurements taken from a prototype AFPM machine. The advantages and disadvantages of the approach are then outlined and conclusions drawn. The developed thermofluid model is shown to perform thermal analyses with reasonable accuracy.
